Sony Xplod CDX-MP30 Troubleshooting

When you start the stereo, the screen does not light up or turn on.

Try resetting the stereo by pressing the reset button located on the front of the device.

If this does not work, turn off your car, then turn it back on and see if that resolves the issue.

It is possible that the LCD bulb in the stereo's screen has expired. You can refer to our guide on how to replace the LCD.

If replacing the LCD does not resolve the issue, then it is most likely the motherboard that is the issue. To do this you can follow the front screen motherboard repair guide.

No matter what you do, the stereo will not turn on.

Before trying to take apart your stereo, make sure all of your stereo's connections are wired in securely, ensuring its functionality.

Turn off your car, then turn it back on and see if the stereo responds now.

The power supply could have gone bad in your stereo. Please refer to our guide for replacing the power supply.

If replacing the power supply did not fix the issue, then it is likely that the motherboard is causing the problem. Refer to our guide on replacing the motherboard in your stereo.

You are unable to insert a new CD into the disk tray.

There may be a CD already in the tray. Press the eject button on the front display and remove the CD currently in the tray.

If this does not work, press the reset button located on the front of the screen, and see if that ejects the disk.

It is possible that there is another CD jammed into the disk tray. We have a guild on how to remove a jammed CD.

You insert a new disk properly, but its automatically ejected.

If the ambient temperature reaches 50 degrees Celsius (122 degrees Fahrenheit) or higher, then the stereo will not function properly. Leave the stereo off for a little bit, to let the parts sit and cool. After a few minutes, turn it back on and try inserting a disk again.

Turning either the volume or tuner knobs on the front of the stereo have no effect.

Before replacing the knobs, try resetting the stereo by pressing the reset button on the front of the screen.

If this does not work, turn off your car completely, turn it back on, and then try the knobs again.

The music from your CD skips.

If your stereo is installed at an angle greater than 60 degrees, then is will cause your CD to skip. Re-install the stereo at an angle lower than 60 degrees.

It is possible that your CD is dirty or defective. Clean the disk and then play it again.

Stereo will not play music, or function properly.

It is possible that that CD was inserted upside-down. Eject the CD and make sure it is inserted right-side-up, with the shiny part facing down.

Your CD may not be read if it has an excessive amount of fingerprints or smudges on it. Clean the disk and insert it again to see if this helps the issue.

Make sure the VOL knob is not turned all the way counter-clockwise. Turn the knob clock-wise to increase the volume.

Set the fader control to the center position for a two-speaker system.

Cancelling the ATT function can sometimes fix the issue as well. Adjust this by pressing the ATT button located on the front of the screen.

Checking to make sure the audio/in and audio/out plugs are input correctly. If this could be the problem please refer to our audio-in/audio-out replacement.
